Further absorption of potassium (K) onto the AKAKABA…stacked surface of graphite results in the formation of a (2 × 2) superstructure. A test of seven different surface-structure models with dynamical LEED calculations indicated that an A-(2 × 2)Kα-A-(2 × 2)Kβ-AB…stacked model results in intensities in good agreement with the measured diffracted intensities. Such a model is consistent with structures observed in bulk graphite for intercalated potassium.
